uh...no clue. the last time i bought steak i just made sure it didn't look icky (gray patches, oil-slick-rainbow patches), and checked the expiration date to be sure that it had a few days left.

ask someone who works there, maybe?

also, i haven't cooked steak in ages so i'll be googling. lemme know if there are any particular flavors you want with/on it and i'll see if we have the stuff for it.
